Am I in the wrong?

This is a long story but I'm going to make it short. I was with a man for 4 years and we broke up about a year ago now. After that breakup I became a stripper and lost all respect for myself, I was forced into doing drugs, sexually abused there etc. It was a really rough time for me and I hate myself for it. I am now with a new man, who is now my fiancé. He knows about my past and hates it especially the fact that I was a stripper. I've always been the type of lady to hate women showing off their naked bodies to anyone else but their partner. I dislike porn anything that has that sort of stuff in it. Maybe I'm old fashioned but a women's body is a beautiful thing and to show it off in my opinion is disgusting. My partner knows how I feel about this all and has disrespected me a few times. He has asked to go to a strippers with me knowing what's happened to me. We have just moved in together and we were finishing our bedroom up and he pulls out this massive painting of a naked women, not in a pretty pose either and I just felt sick. I want to feel comfortable in my own room and I asked him nicely if he cannot put the painting up and he has seriously cracked it. Someone help am I over reacting? Because I think not, I don't want a massive painting of some disgusting porno women in my bedroom.
